Advantages: Compared with industrial grade, it has good crystalline state, low chroma and high light transmittance. After purification, the Content is higher than that of industrial grade. 0.1%, sebacic acid Content is less than 0.05%, the particle size can reach 30 microns after powdering, easy to mix and absorb.
Main Uses:
1. It has good permeability to the skin. Use in cream cosmetics can increase the skin's absorption function. It can effectively inhibit the acne bacteria on the skin and block the production of fatty acids. It can also slow the growth of keratinocytes. 2. Blocking the formation of melanin can prevent the formation of spots, and has the functions of brightening skin and whitening.
2. Rhododendron acid or its zinc salt is compatible with vitamin B6 for hair care products. It is suitable for the treatment of male hormonal alopecia with strong endocrine in men and stimulates hair growth at the same time.
